Gaming device having free spin mode with symbol elimination



Abstract

A bonus game that operates in combination with a slot machine base game is
     provided. The bonus game includes a series of free spins or free
     evaluations in which symbols of a set of symbols are generated. The free
     spins also generate executor symbols that alone or in accumulation cause
     one of the symbols of the set to be eliminated or replaced. In either
     case the symbols remaining in the set have a higher probability of being
     generated and a higher probability exists that a larger award paying
     combination of the remaining symbols will be generated. The elimination
     sequence can be repeated a number of times further increasing the
     probability of generating a higher paying award for the player. The
     present invention is operable with different types of base games such as
     slot and poker.

BACKGROUND OF THE INVENTION


Gaming device manufactures have long provided gaming machines employing a plurality of reels, wherein the reels each have a plurality of symbols.  In the 1930's, gaming device manufacturers provided a three reel gaming device, wherein each reel
had ten stops, which produced a thousand combinations.  One way for the manufacturers to increase the number of combinations was to increase the size of the reel and to add more stops.  During the next four decades, the reels in the gaming devices
increased to twenty stops.  In the 1970's, manufacturers developed a twenty-two stop reel machine, in the early 80's a twenty-five stop reel machine, and in 1985, International Game Technology, the assignee of the present invention, developed a
thirty-two stop reel machine.  This machine had 32,768 possible combinations.


Another way manufacturers increased the number of combinations was to add reels.  In 1955, a manufacturer produced a four-reel slot machine, which increased the number of combinations on a twenty stop machine to 160,000.  In the middle 1970's, a
manufacturer produced the first five-reel slot machine, which had twenty-two stop reels and produced combinations in excess of five million.


The next advancement in the effort to produce more payout combinations was the video or CRT screen slot machine, wherein the reels were simulated as opposed to mechanical.  Video slot machines do not have mechanical drums or reels which rotate,
do not need to precisely stop the same at certain positions and are therefore not limited by a maximum allowable drum radius.  Each reel can have a virtuality unlimited number of stops.  Initially, the Nevada gaming Commission limited the stops on the
video machines (e.g., eighty-four stops on a three reel machine) but has since removed the limit.  In 1989, a particular video reel machine employed reels having hundreds of stops and more than millions of combinations.


The total number of combinations affects the percentage of time that a player will obtain a particular winning combination as well as the overall payout percentage of the machine.  For example, a three reel machine having twenty-two stops per
reel, where the first reel has two oranges, the second reel has three oranges, and the third reel has seven oranges will yield an orange, orange and orange combination 42 times in every 10,648 plays (22.times.22.times.22) or 0.39% of the time.  If the
orange, orange, orange combination pays 20 coins, then the total coins paid is 20.times.42 or 840 coins in every 10,648 plays.  Adding the total coins paid for each winning combination and dividing that number by 10,648 yields the machine's total payout
percentage.


In the known gaming systems the percentage of obtaining a winning combination is set.  In certain known progressive gaming machines, the payout of a grand prize grows each time a player plays the machine.  The increasing payout increases the
total coins paid as shown above, which in turn increases the overall payout percentage.  Nevertheless, the percentage of times that a player will receive one of the combinations remains constant.


Free spins have also been provided in slot games.  Upon winning free spins, the reels can auto-generate a number of outcomes and provide the player credits from winning symbol combinations occurring in the outcomes.  Free spins provide an avenue
for adding fun and excitement to standard gaming, while maintaining consistency with the slot base game and enabling the slot game to be played and displayed on simulated or electromechanical reels.


To increase player enjoyment and excitement, it is desirable to provide players with new types of gaming devices that attract the player and keep the player entertained.


SUMMARY OF THE INVENTION


The present invention provides a gaming machine including a base game operable upon a wager and a bonus game that operates in combination with the wagering base game.  The bonus game or mode includes a series of free activations such as free
spins or free deals in which a symbol or card can be eliminated from a set of symbols.  The player plays the base game until triggering a free spin sequence for slot games or a free deal sequence for card games such as poker according to the base game. 
In the free spin or deal sequence or mode, the gaming device generates sets of symbols, which can be the same or different as the symbols used in the base game.  The gaming device can also generate wild symbols in the free spin or deal sequence or mode.


In the free spin or free deal sequence or mode, the gaming device symbols also includes one or more executor symbols.  The executor symbols are randomly generated in one embodiment.  In one embodiment, the executor symbols cause a meter to
increment.  When the meter increments to a designated or particular point or level, the gaming device eliminates or removes a symbol from the set of symbols or a card from the deck of cards subsequently used in the free spin deal sequence (i.e., in one,
a plurality, or all of the subsequent free spins or activations).  In other words, the gaming device will not generate that eliminated or removed symbol or card again in the free spin mode (i.e., in one, a plurality, or all of the subsequent free spins
or activations).  Thus, the gaming device can prevent the eliminated symbol from subsequently be generated in a free spin.  In one embodiment, the eliminated symbol is not actually eliminated from the set or removed from the reels; but, rather the
processor of the gaming machine prevents that symbol from being generated in one or more subsequent free spins.  In one embodiment, if the eliminated symbol is initially selected to be generated, the processor can cause a generation of another remaining
symbol (such as by re-spinning a reel to generate another symbol on the reel).  The removal of the symbol or card increases the likelihood of the player achieving multiple combinations of the other symbols such as a same symbol or card in subsequent free
spins, free deals, or free activations of the remaining symbols or cards.  That is, the removal of a symbol or card increases the likelihood of generating each of the remaining symbols or cards.  Accordingly, a free spin or free deal game is provided
that over time becomes on average more lucrative on average for the player.


The free spin or free deal sequence includes multiple embodiments.  In one embodiment, the symbol or card is merely removed from the free spin, free deal or free activation set of symbols, lessening the total number of different symbols that can
be generated.  In an alternative embodiment, the symbol is replaced by another symbol.  The symbol is replaced either with a wild symbol or one of the remaining other symbols or cards of the set or deck, respectively.  In one such embodiment, each
occurrence of the symbol to be removed in the set is transformed or replaced by a wild symbol.  In these two alternative embodiments, the total number of symbols that can be generated does not change; however, the total number of different symbols does
change.  In the alternative embodiments, the likelihood of generating a combination or multiple ones of any one of the remaining symbols increases.


The free spin or free deal sequence in one embodiment continues to generate outcomes until a number of provided free spins or free deals is exhausted.  The number provided can be dependent upon one or more different factors, such as the factors
described below.  In one embodiment, for example, the player receives more free spins or free deals by generating more triggering symbols in the base game.  In another embodiment, the number of free spins is based at least in part on the player's wager
in the primary game which triggers the free activation mode.


During the series of free spins or free deals, the symbol elimination or replacement meter can be incremented to its final position multiple times, thereby eliminating or replacing multiple symbols throughout the course of the free generation
sequence.  Accordingly, the game over time on average becomes more favorable to the player as larger combinations of paying symbol combinations are more likely to occur.


After the free spin sequences of the present invention are provided, credits obtained from the free spins are paid to the player during a credit roll-up.  The player can then resume playing the base game.


It is therefore an advantage of the present invention to provide a fun and exciting slot machine or poker bonus game.


A further advantage of the present invention is to provide an improved free spin game.


Yet another advantage of the present invention is to provide a free generation game adaptable to multiple types of gaming devices such as slot and poker.


Moreover, it is an advantage of the present invention to provide a bonus game that uses base game symbols or cards in a fun and exciting way to provide a bonus game that is different yet related to the base game.


Additional features and advantages of the present invention are described in, and will be apparent from, the following Detailed Description of the Invention and the figures.

removal meter 70, the function of each of which is described below.


Poker Base Game Generally


In one embodiment, a base or primary game may be a poker game wherein gaming device 10 enables the player to play a conventional game of video poker and initially deals five cards, all face up, from a virtual deck of fifty-two cards.  As seen in
FIGS. 12 to 14, playing cards may be dealt to positions 94a to 94c as in a traditional game of cards or in the case of gaming device 10, the cards may be randomly selected from a predetermined number of cards.  If the player wishes to draw, the player
selects the cards to hold by using one or more input devices, such as pressing related hold buttons or touching a corresponding area on a touchscreen.  After the player presses the deal button, processor 12 of gaming device 10 removes the unwanted or
discarded cards from the display and deals replacement cards from the remaining cards in the deck.  This results in a final five-card hand.  The processor of gaming device 10 compares the final five-card hand to a payout table which utilizes conventional
poker hand rankings to determine the winning hands.  An award based in an embodiment on the credits wagered is provided to the player upon a winning hand.


In another embodiment, the base or primary game may be a multi-hand version of video poker.  In this embodiment, the player is dealt at least two hands of cards.  In one such embodiment, the cards in all of the dealt hands are the same cards.  In
one embodiment each hand of cards is associated with its own deck of cards.  The player chooses the cards to hold in a primary hand.  The held cards in the primary hand are also held in the other hands of cards.  The remaining non-held cards are removed
from each displayed hand and replaced with randomly dealt cards.  Since the replacement cards are randomly dealt independently for each hand, the replacement cards will usually be different for each hand.  The poker hand rankings are then determined hand
by hand and awards are provided to the player.


Bonus Game


In one embodiment, in addition to winning credits in a base or primary game, the gaming device may also give players the opportunity to win credits in a bonus or secondary game or bonus or secondary round.  The bonus or secondary game enables the
player to obtain a bonus prize or payout in addition to the prize or payout, if any, obtained from the base or primary game.  In general, a bonus or secondary game produces a significantly higher level of player excitement than the base or primary game
because it provides a greater expectation of winning than the base or primary game and is accompanied with more attractive or unusual features than the base or primary game.


In one embodiment, gaming device 10 includes a program code that causes processor 12 to automatically begin a bonus round when the player has achieved a triggering event, a qualifying condition or other designated game event in the base or
primary game.  In another embodiment illustrated below in the paytables of FIGS. 3 and 5, the triggering event or qualifying condition may be a selected outcome in the primary game or a particular arrangement of one or more indicia on a display device in
the primary game, such as the number seven appearing on three adjacent reels along a payline 52 in the primary slot game embodiment seen in FIGS. 1A and 1B.  In another embodiment, the triggering event or qualifying condition may be triggered by
exceeding a certain amount of game play (number of games, number of credits, amount of time), earning a specified number of points during game play or as a random award.


In one embodiment, once a player has qualified for a bonus game, the player may subsequently enhance their bonus game participation by returning to the base or primary game for continued play.  Thus, for each bonus qualifying event, such as a
bonus symbol, that the player obtains, a given number of bonus game wagering points or credits may be accumulated in a "bonus meter" programmed to accrue the bonus wagering credits or entries towards eventual participation in a bonus game.  The
occurrence of multiple bonus qualifying events in the primary game may result in an arithmetic or geometric increase in the number of bonus wagering credits awarded.  In one embodiment, extra bonus wagering credits may be redeemed during the bonus game
to extend play of the bonus game.


In one embodiment, no separate entry fee or buy in for a bonus game need be employed.  That is, a player may not purchase an entry into a bonus game.  The player must win or earn entry through play of the primary game, thereby encouraging play of
the primary game.  In another embodiment, qualification of the bonus or secondary game could be accomplished through a simple "buy in" by the player if, for example, the player has been unsuccessful at qualifying for the bonus game through other
specified activities.


Server Controlled Gaming Devices


In one embodiment, as illustrated in FIG. 2B, one or more of the gaming devices 10 of the present invention may be connected to a data network or a remote communication link 58 with some or all of the functions of each gaming device provided at a
central location such as a central server or central controller 56.  More specifically, processor 12 of each gaming device may be designed to facilitate transmission of signals between the individual gaming device and the central server or controller.


In one embodiment, the game outcome provided to the player is determined by central server or controller 56 and provided to the player at gaming device 10 of the present invention.  In this embodiment, each of a plurality of such gaming devices
10 are in communication with the central server or controller 56.  Upon a player initiating game play at one of the gaming devices, the initiated gaming device communicates a game outcome request to the central server or controller 56.


In one embodiment, central server or controller 56 receives the game outcome request and randomly generates a game outcome for the primary game based on probability data.  In another embodiment, the central server or controller 56 randomly
generates a game outcome for the secondary game based on probability data.  In a further embodiment, the central server or controller 56 randomly generates a game outcome for both the primary game and the secondary game based on probability data.  In
this embodiment, the central server or controller 56 is capable of storing and utilizing program code or other data similar to processor 12 and memory device 14 of gaming device 10.


In an alternative embodiment, the central server or controller 56 maintains one or more predetermined pools or sets of predetermined game outcomes.  In this embodiment, the central server or controller 56 receives the game outcome request and
independently selects a predetermined game outcome from a set or pool of game outcomes.  The central server or controller 56 flags or marks the selected game outcome as used.  Once a game outcome is flagged as used, it is prevented from further selection
from the set or pool and cannot be selected by the central controller or server 56 upon another wager.  The provided game outcome can include a primary game outcome, a secondary game outcome, primary and secondary game outcomes, or a series of game
outcomes such a free games.


The central server or controller 56 communicates the generated or selected game outcome to the initiated gaming device 10.  Gaming device 10 receives the generated or selected game outcome and provides the game outcome to the player.  In an
alternative embodiment, how the generated or selected game outcome is to be presented or displayed to the player, such as a reel symbol combination of a slot machine or a hand of cards dealt in a card game, is also determined by the central server or
controller 56 and communicated to the initiated gaming device to be presented or displayed to the player.  Central production or control can assist a gaming establishment or other entity in maintaining appropriate records, controlling gaming, reducing
and/or preventing cheating or electronic or other errors, reducing or eliminating win-loss volatility and the like.


In another embodiment, one or more of the gaming devices of the present invention are in communication with a central server or controller 56 for monitoring purposes only.  That is, each individual gaming device 10 randomly generates the game
outcomes to be provided to the player and the central server or controller 56 monitors the activities and events occurring on the plurality of gaming devices.  In one embodiment, the gaming network includes a real-time or an on-line accounting and gaming
information system operably coupled to the central server or controller.  The accounting and gaming information system of this embodiment includes a player database for storing player profiles, a player tracking module for tracking players and a credit
system for providing automated casino transactions.


A plurality of the gaming devices of the present invention are capable of being connected to a data network.  In one embodiment, the data network is a local area network (LAN), in which one or more of the gaming devices are substantially
proximate to each other and an on-site central server or controller as in, for example, a gaming establishment or a portion of a gaming establishment.  In another embodiment, the data network is a wide area network (WAN) in which one or more of the
gaming devices are in communication with at least one off-site central server or controller.  In this embodiment, the plurality of gaming devices may be located in a different part of the gaming establishment or within a different gaming establishment
than the off-site central server or controller.  Thus, the WAN may include an off-site central server or controller and an off-site gaming device located within gaming establishments in the same geographic area, such as a city or state.  The WAN gaming
system of the present invention may be substantially identical to the LAN gaming system described above, although the number of gaming devices in each system may vary relative to each other.


In another embodiment, the data network is an internet or intranet.  In this embodiment, the operation of gaming device 10 can be viewed at the gaming device with at least one internet browser.  In this embodiment, operation of gaming device 10
and accumulation of credits may be accomplished with only a connection to the central server or controller 56 (the internet/intranet server or webserver) through a conventional phone or other data transmission line, digital signal line (DSL), T-1 line,
coaxial cable, fiber optic cable, wireless gateway or other suitable connection.  In this embodiment, players may access an internet game page from any location where an internet connection and computer, or other internet facilitator are available.  The
expansion in the number of computers and number and speed of internet connections in recent years increases opportunities for players to play from an ever-increasing number of remote sites.  It should be appreciated that enhanced bandwidth of digital
wireless communications may render such technology suitable for some or all communications according to the present invention, particularly if such communications are encrypted.  Higher data transmission speeds may be useful for enhancing the
sophistication and response of the display and interaction with the player.


In another embodiment, a plurality of gaming devices 10 at one or more gaming sites may be networked to a central server 56 in a progressive configuration, as known in the art, wherein a portion of each wager to initiate a base or primary game
may be allocated to bonus or secondary event awards.  In one embodiment, a host site computer is coupled to a plurality of the central servers 56 at a variety of mutually remote gaming sites for providing a multi-site linked progressive automated gaming
system.  In one embodiment, a host site computer may serve gaming devices distributed throughout a number of properties at different geographical locations including, for example, different locations within a city or different cities within a state.


In one embodiment, the host site computer is maintained for the overall operation and control of the system.  In this embodiment, a host site computer oversees the entire progressive gaming system and is the master for computing all progressive
jackpots.  All participating gaming sites report to, and receive information from, the host site computer.  Each central server computer 56 is responsible for all data communication between gaming device 10 hardware and software and the host site
computer.


Free Spin (Deal) Game With Symbol (Card) Elimination


Referring now to FIG. 3, one of the display devices 16 or 18 displays one embodiment of a paytable of the present invention.  The paytable sets forth winning symbols and winning symbol combinations as well as the number of credits paid to the
player for achieving such symbols or combinations.  The amount of credits paid corresponds to a likelihood that a particular symbol or symbol combination will appear on the reels 54.  For example, two bars as illustrated pays one credit, while a single
"V" symbol pays 100 credits.  The "V" symbol is accordingly less likely to appear on reels 54 than is the bar symbol.


The paytable illustrates that certain symbols, such as the star, the banana, and the "V" symbols provide a payout for a single appearance of the symbol on the leftmost reel.  The winning combinations in general begin from the left side of the
reels and extend incrementally towards the right side of the reels.  This feature is common among gaming machines and is important to the present invention in one embodiment illustrated below.  The symbols alternatively appear at any desired location
along the reels.


In one embodiment, a designated symbol or symbol combination triggers the wild symbol and free spin operation of the present invention.  In the illustrated paytable, the symbol "T" appearing on an active payline triggers the free spin bonus. 
Alternatively, the triggering symbol need not appear on an active payline.  Further, the triggering of the free spin game could have different or additional requirements, such as requiring: (i) a player's wager or a component thereof to be at a certain
level such as max bet; (ii) that the player have played at least a certain number of games; (iii) have wagered a certain amount; (iv) have lost a certain amount.  This could alternatively or additionally be based on other requirements such as a player's
account such as in relation to a player tracking card.  The winning symbols and symbol combinations, as well as the illustrated credit amounts, are used below in the following examples that highlight the features and advantages of the present invention.


Gaming device 10 provides a number of at least two free spins to the player.  The number of spins provided can depend on different events, such as: (i) being predetermined, (ii) being randomly determined; (iii) being dependent upon the number of
lines played; (iv) being dependent upon the bet per line; (v) being dependent upon the total bet; (vi) being dependent upon a base game outcome; or (vii) any combination thereof.


FIG. 4 illustrates a separate screen of one of the display devices 16 or 18 that illustrates a paytable used in the free spins sequence of the present invention and explains various features of the free spin sequence.  FIG. 4 illustrates that the
free spin includes six symbols A, B, C, D, F and G. The paytable also indicates that the free spin sequence includes a wild symbol W, which when generated represents or can function as any of the symbols A, B, C, D, F and G that are being used at the
start of the game.  The paytable also illustrates that the free spin sequence includes at least one execution symbol EX.  Execution symbol EX increments a symbol removal meter 70 discussed below with regard to FIG. 7.  As discussed herein, when the meter
70 reaches a particular point, one of the symbols A, B, C, D, F or G is removed from the set of available symbols to be subsequently generated, thereby increasing the player's odds of obtaining a winning combination of the remaining symbols in the free
spin sequence.


The paytable of FIG. 4 also shows the pays or payouts for various combinations of symbols A, B, C, D, F and G. In particular, the paytable shows that the player is paid two hundred credits for achieving the same five of the A, B, C, D, F or G
symbols on a payline that has been active during the previous base game spin.  In an alternative embodiment (shown in parentheses), the five symbols can alternatively appear in a scatter arrangement on reels 54a to 54e.  The player receives thirty
credits for the generation of four of the same A, B, C, D, F or G symbols on active payline (scatter in an alternative embodiment).  Furthermore, the player receives five credits if gaming device 10 generates the same three of the A, B, C, D, F or G
symbols on an active payline (alternatively in a scatter arrangement).  Also, the player receives two credits for achieving the same two of the A, B, C, D, F or G symbols on an active payline (alternatively in a scatter arrangement).


The paytable of FIG. 4 also shows three different embodiments for the symbol elimination free spin sequence of the present invention.  In a commercial version, the screen of FIG. 4 would only show the embodiment that is actually employed in
gaming device 10.  For ease of illustration, the three different embodiments are each shown in FIG. 4.  In an alternative embodiment, each of the three embodiments could be employed in a single gaming device 10, wherein gaming device 10 selects one of
the elimination sequences when the player enters the bonus spin sequence of the present invention.


In the first elimination embodiment, gaming device 10 eliminates one of the symbols A, B, C, D, F or G from the symbol set when the free spin sequence generates the execution symbol EX a preset number of times, which is three in this example.  By
eliminating one of the symbols from the free spin set and causing the remaining symbols to have a higher probability of occurrence, gaming device 10 increases the chances of the player achieving the winning symbol combinations using the remaining symbols
shown in the paytable.  In one alternative, the eliminated symbols can be replaced with the other remaining symbols which also increases the occurrence of such remaining symbols.  As discussed above, a wild symbol W in one embodiment can also replace the
eliminated symbol.  The wild symbol would function as one of the other remaining symbols.  The wild symbol would not function as the eliminated symbol in the preferred embodiment.  The wild symbol which replaces the symbol eliminated in the free spin
sequence increases the player's chances of achieving one or more winning combinations (which do not include the eliminated symbol) in the free spin sequence.


In the second and third elimination embodiments, one of the symbols of the set is replaced or eliminated when the player obtains a preset number of execution symbols such as three symbols.  In one alternative embodiment, the symbol is replaced
with a wild symbol that can function as or represent each of the remaining symbols of the set.  In another embodiment, the replaced symbol is replaced with one of the remaining symbols.  This increases player's chances of generating the winning
combinations for the remaining symbols and in particular the chances of obtain winning combinations with a greater number of symbols which provide greater awards.


In the first embodiment, the overall number of reel stop positions is reduced when one of the symbols is eliminated from the set.  In the second and third embodiments, the overall number of reel stops stays the same; however, one of the symbols
is replaced with a wild symbol or one of the remaining symbols of the set.  The reel stops of the replaced symbol will therefore each contain the wild symbol or a remaining symbol.


In one embodiment, an execution symbol can not be eliminated or replaced.  In other embodiments, one or more execution symbols can be eliminated or replaced.


In one embodiment, the particular symbol removed or eliminated is chosen randomly.  In one embodiment, each of the symbols A, B, C, D, F or G is equally likely to be chosen first, second, third, etc., to be eliminated.  The next time the player
accumulates the executor symbol EX the preset number of times, one of the remaining symbols is again chosen randomly to be eliminated.  In an alternative embodiment, the symbols are eliminated according to a predetermined order.  For example, the A
symbol could be eliminated first, followed by the B symbol, the C symbol, etc.


In the symbol replacement embodiments, the symbol to be replaced can be generated randomly or selected via a predetermined order as discussed above in the symbol elimination embodiment.  Further, when the replaced symbol is replaced with a
remaining one of the symbols, the symbol that is selected to replace the replaced symbol is selected randomly or according to a predetermined order.


Referring now to FIG. 5, an alternative paytable is shown on one of the display devices 16 and 18 for a poker game embodiment, which includes a free deal sequence in which hands of cards are dealt repeatedly and sequentially without requiring the
player to place an additional wager, and wherein the player receives credits according to the illustrated paytable.  The paytable of FIG. 5 differs from the paytable of FIG. 4 not only in the base game that is played but also in the fact that in the slot
game, a separate paytable is provided for the free spin sequence, while in the free deal sequence of the poker game, the same paytable and same paying combinations are used both in the base game and in the free deal sequence.  Furthermore, the symbols
used in the base game and free deal sequence are the same.  In a slot embodiment alternative to the one shown above in FIGS. 3 and 4, the present invention alternatively uses a single set of symbols and paytable in both the base and free spin sequences. 
Thus, the present invention contemplates having completely separate sets of symbols in the base and free spin or deal sequences, using some of the symbols or cards in both base and free generation sequences, or using the same set of symbols or cards in
both the base and free spin or free deal sequences.


The paytable shown in FIG. 5 illustrates that for the base poker game and the free deal sequence: a royal flush pays three hundred credits; five-of-a-kind pays one hundred credits; a straight flush pays fifty credits; four-of-a-kind pays
twenty-five credits; a flush pays fifteen credits; a full house pays ten credits; three-of-a-kind pays six credits; a straight pays four credits; two pairs pays three credits; and jacks or better pays two credits.


FIG. 5 illustrates that a triggering T symbol in combination with jacks or better triggers the free deal sequence of the present invention.  In an alternative embodiment, only the triggering T symbol is required.  In a further alternative
embodiment, any standard card or combination of playing cards triggers the free deal sequence and a separate trigger symbol is not used.  Similarly, a base game slot machine symbol or combination thereof may be used to trigger the free spin slot sequence
as opposed to a dedicated trigger symbol.


FIG. 5 also provides a description of the free deal sequence.  Here, the Jokers Wild card is activated and represents each remaining face card in the poker deck.  The illustrated embodiment of the free deal sequence operates differently than the
free spin sequence of the slot game because a dedicated execution symbol is not provided in the free deal sequence.  That is, as illustrated, the appearance of an ace after a free deal generation increments the symbol removal or replacement meter.


The free deal sequence like the free spin sequence includes multiple different embodiments.  In one embodiment, an accumulation of a preset number, e.g., three, aces causes gaming device 10 to eliminate one of the remaining card denominations
from the deck.  In a second embodiment, the accumulation of, e.g., three aces causes one of the remaining card denominations to be replaced with a Joker card.  In a further alternative embodiment, the accumulation of three aces causes a remaining one of
the cards to be replaced with another one of the remaining cards.


In the third embodiment, one of the cards, e.g., the Two of Hearts, Diamonds, Spades or Clubs, is replaced with another denomination, such as an extra set of Jacks.  In such a case, the deck would then include a total of eight Jacks.  It is
believed that this embodiment as well as the Jokers Wild replacement embodiment will significantly increase the player's chances of obtaining higher paying card combinations, such as four-of-a-kind and a flush.  As before, the gaming device 10 can be set
so that the number of accumulated cards needed to eliminate or replace a card is at any suitable level and is not limited to accumulating the illustrated three cards.


As discussed above with the free spin sequences, the order in which card denominations are eliminated from the deck can be randomly determined or determined via a preset order.  Further, in the third embodiment, the card that replaces the
replaced card can be randomly determined or determined via a preset order.


Referring now to FIGS. 6 to 11, one example of the slot machine free spin sequence of the present invention is illustrated.  FIG. 6 shows one of the display screens 16 or 18 displaying the reels, paylines, indicators and selectors described above
are shown on one of the display devices 16 or 18, namely, five reels 54a to 54e and five paylines 52a to 52e.  Display device 16 or 18 shows the total credit display 20, lines played display 64, bet per line display 66, total bet display 22, change
paylines input 30a, change bet per line input 30b and play button 34.  Free spins meter 68 is also shown in FIGS. 7 to 11.


FIG. 6 illustrates that the player playing the base game has a current total of one hundred credits and has just generated the free spin slot machine bonus of the present invention by generating the triggering "T" symbol on payline 52a.  The
player is provided ten free spins as indicated by meter 68 shown in FIG. 7.  Gaming device 10 arrives at ten free spins via any of the methods discussed above.  In one implementation, the player is provided more free spins if a single triggering symbol
"T" lands on multiple active paylines, such as on paylines 52c and 52e, or if two or more triggering symbols "T" are generated each on single paylines.


Gaming device 10 has accordingly provided an audio, visual or audiovisual message 82 informing the player that gaming device 10 has triggered the free spin sequence with ten free spins and all lines active.  In an embodiment, the player receives
more free spins by obtaining multiple triggering T symbols on one or more active paylines.


In FIG. 7, the spins remaining meter 68 is illustrated in addition to the symbol elimination or replacement display 70.  In an embodiment, display 70 follows a theme of gaming device 10.  Here, display or meter 70 includes a guillotine having a
blade 72 and a basket 74.  The blade is sequentially raised to first, second and third levels 76.


FIG. 7 also illustrates the symbols currently used in the free spin set via audio, visual or audiovisual message 84.  In particular, all symbols A, B, C, D, F and G as well as the wild and executor symbols EX can be generated randomly on reels
54a to 54e.  The illustrated embodiment includes a predetermined order of symbol removal, as indicated by message 88.  In particular, the symbols are removed in alphabetical order, namely, A, B, C, D, F and G. Alternatively, the symbols are removed in
any desired preset order or in a randomly generated order.  A message 86 is also provided showing that the first or next symbol that is removed is the symbol A. Accordingly, symbol A appears beneath the blade 72 of the guillotine display 70.


The free spin sequence in one embodiment is auto-generating and has generated a first free spin outcome shown in FIG. 7.  Accordingly, spins remaining meter 68 shows a transition from the original ten provided free spins to nine free spins.  In
an alternative embodiment, the free spins are activated upon an input by the player.  Gaming device 10 provides a message 90 indicating that one executor symbol EX has been generated on an active payline (all five paylines active in this example) and
causes blade 72 of guillotine 70 to move up one slot.  Display 70 accordingly shows the original position of blade 72 shown in phantom and the new position of blade 72 shown in solid.  Gaming device 10 also shows a message 92 indicating that the player
has won two credits on payline 1 (for receiving the "G", "G" combination on payline 52a).  Accordingly, the player's credits increase from one hundred to one hundred two as shown in credit display 20.


Referring now to FIG. 8, gaming device 10 auto-generates a second free spin, as shown in spins remaining display 68.  Message 90 indicates that two executor symbols EX have been generated.  As seen, an executor EX symbol appears on each of
paylines 52b and 52d.  The two executor symbols move blade 72 to the top of guillotine 70.  Blade 72 then falls and chops symbol A into basket 74.  As seen by first, second and third positions 76, blade 72 moved from the first position 76 to the third
position 76, which is the uppermost position.  In an alternative embodiment, a different number of positions is used in meter 70.  In a further alternative embodiment, the meter 70 is not employed and one of the symbols of the free spin sequence is
eliminated upon each generation of one of the executor symbols.


Message 92 indicates that the free spin outcome in FIG. 8 has generated five credits for the "B, B, B" combination appearing on payline 3 and five credits for the same combination appearing along payline 5.  The wild symbol generated on reel 54c
increases the "B, B" win on payline 3 to a three symbol payout.  Accordingly, the player's total credits increases to one hundred twelve as seen in credit display 20.


Referring now to FIG. 9, the symbol A has been eliminated and can no longer be generated on reels 54a to 54e.  In the alternative embodiments described above, the symbol A is either replaced with the wild symbol or with one of the remaining
symbols B, C, D, F and G. Message 84 shows that the symbol A has been crossed out, removed or replaced.  Message 86 indicates that the next symbol to be removed is now the symbol B. Accordingly, symbol B appears below blade 72 in guillotine or meter 70.


For the third spin of FIG. 9, message 90 indicates that the free spin has generated three executor symbols, which has moved the blade to the top or third position on guillotine 70.  Blade 72 is accordingly shown in phantom from its original
position below the first position and in solid in the top position or third position 76.  Arrows are also shown to indicate that blade 72 falls to cut or chop symbol B into basket 74.  Message 92 also indicates that two credits are provided because
gaming device 10 generated the "C, C" combination on payline 52a.  The player's total credits accordingly increase to one hundred fourteen as seen in credit display 120.  Also, the player's remaining spins change from eight to seven as seen in spins
remaining display 68.


Referring now to FIG. 10, an outcome of the fourth free spin is shown.  Message 84 shows that the A and B symbols are crossed out, removed or replaced.  Accordingly, those symbols are no longer available to be generated on reels 54a to 54e.  It
should be appreciated that by eliminating or replacing symbols, the chances of receiving a larger combination of the remaining symbols C, D, F and G along paylines 52a to 52e or in a scatter arrangement increases.


Message 90 indicates that two executor symbols have been generated and have moved blade 72 up two spots to the second position 76.  Guillotine 70 accordingly shows the blade 72, which is reset after each elimination or replacement, displayed in
phantom in the original or reset position.  Blade 72 is shown in solid at the incremented or metered position adjacent to the second position 76.  Message 86 indicates that the current or next symbol that will be removed is symbol C. Accordingly, symbol
C is shown above basket 74 of guillotine 70.


Spins remaining meter 68 shows that the remaining spins have changed from seven to six.  Message 92 indicates that the player has won five credits on payline 52c for the "F, F, W" combination.  Also, the player has won thirty credits for
receiving the "F, F, F, F" combination on payline 52e.  Such larger combinations of symbols have an increased likelihood of occurring in the current free spins because symbols A and B are not available to be generated.  The player's total credits
accordingly increase to one hundred forty-nine as seen in credit display 20.


Referring now to FIG. 11, the outcome of the fifth free spin of the free spin sequence is illustrated.  Message 90 shows that two executor symbols have been generated.  In particular, a single executor symbol appearing on reel 54b is generated
for both paylines 52c and 52e.  Guillotine 70 shows that blade 72 is initially at the second position 76 and only needs to move to the third position 76 before falling to eliminate or replace the C symbol into basket 74.  As discussed, however, gaming
device 10 has generated two executor symbols.  In one embodiment, gaming device 10 does not provide an additional benefit when an extra executor symbol is generated, i.e., more symbols than are needed to increment meter 70 to the final position.  In an
alternative embodiment, blade 72 is reset to the first position 76 in the next free spin as opposed to resetting blade 72 to the original position.  In a further alternative embodiment, a separate bonus is provided to the player, such as a number of
credits or a credit multiplier.


In FIG. 11, guillotine 70 shows blade 72 in solid at the uppermost position 76 and provides arrows indicating that the blade moves to cut or chop symbol C into basket 74.  The next symbol to be removed as shown by message 86 is symbol C. Further,
the next free spin will show the C symbol crossed out.  Accordingly, in the next free spin, only symbols D, F and G as well as the wild symbol W and executor symbol EX are available to be generated.  The player's chances of winning a high value award
will increase again and can potentially increase further if one or more of the symbols D, F and G is eliminated.  Indeed, it is possible that only one paying symbol can remain besides the wild W and executor symbols.


Spins remaining display shows that the player has five remaining spins after the spin of FIG. 11.  Message 92 indicates that the player wins two hundred credits for achieving five D symbols (using two wild symbols W) on payline 52a, five credits
for achieving three F symbols on payline 52b and two credits for achieving two F symbols on payline 52d.  The player's total credits increase accordingly to three hundred fifty-six as shown in credit display 20.


Referring now to FIGS. 12 to 14, one embodiment of the free deal sequence used in combination with the base game of poker is illustrated.  In FIG. 12, audio, visual or audiovisual message 82 is provided to show that the generation of the transfer
symbol T in combination with a pair of kings at positions 94a and 94c has met the jacks or better requirement for triggering the free deal sequence.  Accordingly, the free deal sequence is auto-generated or generated upon a player input in an alternative
embodiment.  The player also receives two credits for obtaining a single of jacks or better at positions 94 and 96.  The player's credits increase accordingly from one hundred to one hundred-two as shown in credit display 20.  The two credits are also
shown in win display 80.


Referring now to FIG. 13, the outcome of the first free deal of the free deal sequence is illustrated.  Ten free spins are provided initially as seen in meter 68 according to any of the factors or determiners described above.  Guillotine 70,
blade 72, and basket 74 discussed above are used again in the free deal sequence.  Alternatively, a different card elimination meter is used.  Further alternatively, a meter 70 is not employed and one of the card denominations is eliminated upon
receiving any of the elimination symbols.  As discussed above, in the illustrated embodiment the elimination symbols are the Ace cards.  Alternatively, a separate and dedicated executor card, such as the executor card EX is used here in the poker
embodiment.


Message 90 of FIG. 13 indicates that the player has received two Ace cards, namely, at positions 94a and 94d.  Blade 72 of guillotine 70 therefore moves from the original position to the second position 76.  Guillotine 70 and message 86 indicate
that the first or next symbol to be removed or replaced is all four of the Two cards.  That is, when the card denomination Two is removed or replaced, all four suits of Two cards are eliminated.  Message 84 indicates that the current cards in the deck
are the Two through Ace denominations as well as one or more Joker cards.  Message 88 also shows the order of removal to be in ascending order of Two, Three, Four, Five, Six, Seven, Eight, Nine and Ten.  Alternatively, a different preset order is used. 
Further alternatively, cards are eliminated or replaced randomly.


In FIG. 13, win meter 80 shows that the player receives three credits for obtaining the two pair combination, Aces and Fives.  The player's total credits therefore increase to one hundred five as seen in credit display 20.  The player's remaining
spins change from ten to nine as seen in spins remaining display 68.


FIG. 14 illustrates the outcome of the second free deal of the free deal sequence.  Message 90 indicates that a single Ace has been generated, which moves the blade 72 of guillotine 70 from the second position 76 to the third position 76 as
illustrated.  Because blade 72 has reached the final or third position, the blade drops and cuts or removes or replaces the Two cards from the deck used in the free deal sequence.  Accordingly, the current cards in the deck as indicated by message 84
changes from Two to Ace to Three to Ace (and the Jokers Wild).  The next card to be removed is the Three denomination as seen in message 86 and in accordance with the order of removal shown in message 88.


The player receives four credits as seen in win display 80 for receiving the straight (using Jokers Wild symbol in position 94e).  The player's total credits therefore increase to one hundred nine as seen in credit display 20.  The spins
remaining display shows the remaining spins changing from nine to eight.


In subsequent free deals, the Two card is no longer generated.  Therefore, the odds of obtaining multiple ones of any remaining cards are increased.  As the player continues to eliminate cards from the deck, the player's chances of obtaining a
higher combination of any of the remaining cards further increases.  Again, as with the free spin sequence, if the player generates more position moves than are needed to bring blade 72 to the top or third position 76, the blade can begin anew at the
